Abstract
PURPOSE: A water-soluble cationic high polymer, a water-soluble alkali metal salt and an acid are added to a high molecular weight latex to form the transparent serum, thus producing coagulated polymer particles that can be readily washed with high efficiency.
CONSTITUTION: To a high molecular weight latex, preferably having 10wt% or higher polymer concentration, such as polyacrylate synthetic rubber latex, are added (B) a water-solube cationic high polymer as quarternarized polydimethyl-aminoethyl methacrylate or cationized polyacrylamide, (C) a water-soluble alkali metal salt, and (D) an acid to salt out the polymer latex in the form of fine particles. The amounts of components B, C, and D are 0.02W2 parts, 0.1W20 parts and 1W20 parts per 100 parts by wt by component A respectively.
EFFECT: Since the volume of washing water can be reduced, the disposition of waste water becomes simple.
